Custom Modpack is Vanilla

[JayMan]

Launcher Version: Build 191

Operating System: Windows 7 64x

Description of Problem:

I am making a modpack, I had an old modpack that worked like a charm on the old launcher, I am making a new one now with the brand new Technic Platform...But It seems there arnt any Mods when I compile an launch!

[what i do]

Modify a Minecraft.jar an create a bin folder (empty) then place the modified minecraft.jar in...Then make a WinRAR archive an insert the bin into that...Upload to Dropbox and the Website...Input the code into the launcher,,,It notices it but skips installing it an goes to vanilla!

if i have done anything wrong please correct me!

Thanks
